[InternalMetrics] Create InternalMetricsFlusher

This is used to make sure that InternalMetrics will always get flushed
even if a given method returns early. Any code that uses internal
metrics should make sure that there will always be an
InternalMetricsFlusher, or they will crash in debug mode. This should
make it much harder to introduce a regression that causes unbound
memory increases in the internal metrics logging queue.
